AUGUST CARLSON, OF PEORIA, ILLINOIS.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 491,698, dated February14, 1893.

Application filed April 30, 1892. Serial No. 431,317. (No model.)

To @ZZ whom it may concern:

Be it known that I, AUGUST CARLSON, a citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Car-Couplers; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which Will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to certain new and useful improvements incar-couplers by means of which a car-coupler is provided, being simplein construction, durable and effective for the purpose designed.

More particularly my invention relates to an automatic device purposedto couple by mere contact or by the draw bars being brought together andis accomplished by means of certain hooked-headed pivoted levers actingin conjunction with correspondingly hookedheaded spring levers wherebythe connection or coupling process is performed.

That my invention may be more fully understood, reference is had to theaccompanying drawings in which:

Figure l shows the draw head in duplicate and in position to be lockedor coupled by being borne forward until drawheads contact.

Fig. 2 shows the means of unlocking or uncoupling the device either fromthe top of the car or from the side.

In the drawings, BAB are drawheads and are purposed to be connected withthe cars in the usual manner. They are constructed internally in hollowform but of sufficient (ee) are extensions from and secured to theplates (7i-h).

S-S are springs pui-posed to hold the hooked bars A-A in position.

(it-su) are guide Iianges.

(o o) are pertorations in the ends of the draw bar to provide for use oflink and pin, provided such uses are necessary there being of courseprovided a slot as shown in the middle portion or body and at the endsof the draw bars to provide for the reception of the link. i

In using my improved coupler, it is first apparent that the proportionof the draw-head may not be larger than that of the ordinary and may, infact be made smaller. The same means for attachment to cars are employedas in the usual coupler which provides sufficient up and down playbetween the two drawheads.

In operation for the purpose of coupling, the elemental parts of thedevice having been adjusted as herein shown and the draw-heads borneforward, the hooked bars A-A will contact with and depress the hookedspring levers CAC until, the shoulders pass and the spring levers C-Creacting secure the hooked bars A-A firmly within the respectivedrawheads, thus effectually coupling the cars and providing suicientplay room or space to facilitate the easy starting of the cars. Anytendency of the hooks to become unhooked or the cars uncoupled isovercome by the strong leaf or bar spring C, and also by the pressure ofthe springs (tl-4) to release the coupling is very simple and isaccomplished by merely turning the plate (7L) from the horizontal to aperpendicular position which is accomplished by pressure on theextension (ee,) this turning of the plates (7L-JL) will reverse theposition of the hooked bars AA and also the position of the hookedspring plates C-QC, the same being drawn backward by the chain (n--n)being Wound upon the plates (lt-JL) thus providing a ready release oruncoupling of the draw-head and as soon as the uncoupling process hasbeen performed and the extensions (e-e) has been released, therespective parts of the device return imin these positions by means ofthe springs It will be seen from the device and in its structure thatalarge provision has .been made for the shifting of the cars unequalmotions and for the turning of abrupt curves, this device beingespecially adapted to overcome the disadvantages possessed. by othercouplers in these particulars. Should one ofthe bars bef come released,the connecticngat one side is sufficient to maintain a firm couplingindependent of the action of its opposite side.

In Fig. 2 is showna means for operating the device from the side or topof the car in Which figure, (b)shows aconnectionwith the extension(e).whicl1 forms a toggle joint with the long-bar (f.)whicl1 saidlongbar is pivotedfto the lever. (d) .Whichfsaidlever is supported by ipresence of two witnesses. and to the long bar (f) and held in the claspNow by; depressing eitherl of the said l the upright (7c),- m is a barpivoted to the car levers (myor (d)- the.l uncoupling process isperformed but I do not Wish to be conflnedto this specific means ofcarrying out the un- -f coupling process but that any suitable devicemay be used that Will perform the office satisfactorily.

Having thus fully described my invention, what I claim and desire tosecure by Letters Patent is:

1. In a car-coupler the combination With the draw-head of the pivotedhooked bar A, the turn plate h, carried in the lugs G-G, the springnotched bar C, secured within the body of the draw head and adjacent toa recess therein, all substantially as described and set forth. fr i 2.In a car-coupler `the combination with a draw head of the pivoted hookedbar A se.

cured to the turn plate-h, which said plate is fjournaled, as atG--Gf'to turn andvviththe spring S, to holdfthebarAin place,the spring`hooked bar C connected With the turn plate h, by means of the chainn,the spring-z', the extension e, to which may be connected the loperatingmeans consisting of'thebars Z7- -f-m--(Z.suitablypivoted andsupported,all substantially for the purpose described and set forth.

In testimony-whereof I affix my signature in AUGUST CARLSON.
